D'oh.  You mean building and running libtool inside the calling project.
Good point.

There are 2 easy ways to accomodate:
  i) have the ar wrapper figure out at run-time what it needs to do, and
     leave it in $auxdir ($top_srcdir/build-aux for most projects, but in
     the libtool distro = $top_srcdir/libltdl/config), and uninstalled
     libtool will call it from there.
 ii) have configure figure out what the wrapper needs to do, and build it
     in $builddir (alongside the libtool script).  Uninstalled libtool will
     call it from there.
